Description

Summary

In affected versions, the optional BlueBubbles iMessage channel plugin could accept webhook requests as authenticated based only on the TCP peer address being loopback (127.0.0.1, ::1, ::ffff:127.0.0.1) even when the configured webhook secret was missing or incorrect. This does not affect the default iMessage integration unless BlueBubbles is installed and enabled.

Affected Packages / Versions

  • npm: openclaw < 2026.2.13
  • npm: @openclaw/bluebubbles < 2026.2.13

Details

If a deployment exposes the BlueBubbles webhook endpoint through a same-host reverse proxy (or an attacker can reach loopback via SSRF), an unauthenticated party may be able to inject inbound webhook events into the agent pipeline.

  • 743f4b28495cdeb0d5bf76f6ebf4af01f6a02e5a (defense-in-depth)

Mitigations

  • Set a non-empty BlueBubbles webhook password.
  • Avoid deployments where a public-facing reverse proxy forwards to a loopback-bound Gateway without strong upstream authentication.
